The main objective of this work is to study, develop and establish an approach through the mathematical model of performance CENERG under the term (MC). This model is used to characterize the parameters of photovoltaic systems in the literature. For this, we have considered the required performance is normally measured in standard test conditions (STC), where an average solar spectrum AM 1.5 is used, sunshine is normalized at 1000 W/m², and the cell temperature is set equal to 25°C. Modeling which is presented based on data provided by the manufacturers of solar cells or panels. The mathematical modeling process is performed with the model (MC) in search of the equations governing the operation of LRAER group photovoltaic panels, to that end, we can determine the parameters of the mathematical model (MC). The work also allows showing accuracies, through the comparison of the simulation results obtained with the actual production data (experimental) to ATERSA 75 W modules of the LRAER USTM.
Key words: PV generator model (GPV), CENERG mathematical model, characteristics I (V), characteristics P(V).
